Rancilio Classe 8 manual Connections to be made by the user, Water supply, Electric supply

6.1.Connections to be made by the user

Hook-up must be carried out by qualified personnel in full accordance with federal, state and local regulations.

6.1.1. Water supply (Fig.5)

This equipment is to be installed to comply with the applicable federal, state

or local plumbing codes.

Connections must be installed close to the machine.

●Water drainage pipe 1, having a minimum internal diameter of 30 mm, equipped with a water-trap accessible for inspection.

●Water supply pipe 2, with a 3/8"G cut-off tap.

Make sure that the maximum supply pressure does not exceed 6.5 bar; otherwise, install a pressure reducer.

6.1.2. Electric supply (Fig.5)

The machine is supplied ready for connection according to the required electrical specifications. Before connecting the machine ensure that the plate details comply with those of the electric distribution network.

The electrical connection cable must be directly connected to the connection provided according to current legislation. Ensure that the earthing system is efficient and in compliance with current legal re- quirements.

The earthing system and the lightening protection system must be realized in accordance with the provisions of current legislation.

For the supply network use a cable in compliance with standards with protective conductor (earthing wire). For three-phase power use a cable with 3 conductors ( 3 phases + neutral + earth).

For single phase power supply use a cable with 3 conductors (phase + neutral + earth).

In both cases it is necessary to provide an automatic differential switch 4 (Fig. 5) at the start of the power cable, complete with magnetic release elements in accordance with the identification plate details (Fig. 1). The contacts must have an opening of equal or over 3 mm and with dispersed current protection of 30 mA.

Remember that each machine must be fitted with its own safety elements.

WARNING:

Should the power supply cable be damaged it is to be replaced by the manufacturer or by its technical assistance service or by person with equivalent qualification, in order to pre- vent any risks.

6.2. Preliminary operations (Fig.6)

P O T E N T I A L - E Q U A L I Z I N G CONNECTION

This connection, which is the one called for by several norms, avoids electrical potential differences, building up between any equipment that may be installed in the same room. There is a terminal clip on the under side of the base of the machine to which an external potential-equalizing wire should be connected.

This connection is ABSOLUTELY NECESSARY and must be made right after the machine is installed. Use a wire whose cross-sectional area conforms to the existing norms.

6.3. Connections

●Place the machine on the horizontal surface pre- viously prepared.

Before connecting, thoroughly wash the mains water pipes:

●Leave the water supply taps running at full pres- sure for several minutes.

●Connect to the mains water supply.

●Connect the machine to the socket.

Thoroughly wash all the water pipes of the machi- ne:

●Leave the water supply taps running at full pres- sure.

●Switch on main switch 1 (Fig.7): wait until the boiler fills up to the level set.

●Switch on boiler resistance switch 2 (Fig.7) to begin heating the water in the boiler.

●Operate each unit in order to allow the water to escape for about one minute; repeat the operation twice.

●Deliver steam from the steam jets for about one minute.

●Deliver hot water for about one minute; repeat the operation twice.

●Switch off switches 1 and 2.

●Empty the water from the boiler: see point 10.3.1.

IMPORTANT

Should the machine not deliver water for over 24 hours, wash the internal components be- fore beginning work, repeating the operations as described above.
